4218 GF STRÖMAX-circuit regulating valve in a flanged version is available in no-
minal sizes of DN 50 to DN 300. All HERZ valves are factory-equipped with test
points, which can be upgraded with extended test points. The flanged upper parts
of HERZ 4218 GF STRÖMAX are made of cast iron.
The pre-setting marker is fastened as a tag above the valve or pipe. The setting of
the respective valve is marked by cutting or breaking off the teeth at the figures for
full and partial turns. This permits checking and/or restoration of the original pre-
setting made on the occasion of the system set-up after servicing without having
to rely on documentation.
Presetting
1. Set the hand wheel to the desired position (Digital display on handwheel)
2. Red numbers are 1/10 of turn, blue numbers are a full turn.
3. The presetting spindle is beneath the cover. The spindle can be adjusted with an 8mm screwdriver.
To preset turn anti clockwise up to stop. The valve is now able to close and open back to the preset position. Replace the cover on the handwheel.
4. The pre-setting marker is fastened as a tag above the valve or pipe. The setting of the respective valve is marked by cutting or breaking off the teeth
at the figures for full and partial turns. This permits checking and/or restoration of the original pre-setting made on the occasion of system set-up
after servicing without having to rely on documentation.
The setting of flowrate is achieved with a measuring device refering to the flow charts. Please see the operating instructions from the measuring device.

The differential pressure is measured by an appropriate measuring device and the specific flow rate is determined. All HERZ-measuring
computers directly determine the corresponding flow rate. The flow can be limited by default. The preset value remains the same even
when the valve is closed. The presetting is displayed digitally on handwheel.

Presetting
The valve will be delivered in opened position. The pre- setting permits the maximum possible stroke. when the valve is fully closed, the hand wheel
digital display will indicate 0.0
1. Set the hand wheel to the desired position (Digital display on handwheel).
2. Remove the hand wheel securing screw, the handwheel should not be removed.
3. The presetting spindle is now accessible, screw in with a screwdriver blade width 3 x 60 until stop position is reached.
4. Replace the hand wheel securing screw.
5. To mark the adjusted position on the presetting marker and fix it on the valve.

Function
The butterfly valves can be used as isolating and regulating valves, which is achieved by the lever locking in the notch plate.
The lever is made of fiberglass-reinforced polyamide with spring-activated locking mechanism and integrated locking hole.
The top flange is made for the standard gears and actuating drives according to an ISO 5211.
The rubber liner protects the body against internal corrosion. No additional seals are required.
After final mounting the body of the butterfly valve is tested on body strength, body leakage, seat tightness and functionality according to an ISO 5208.
Field of application
Suitable for water and air systems in heating, cooling, air conditioning, ventilation, fire fighting applications and for agriculture. The valves are suitable for
water and air.
The butterfly valves have the body Type “BA, WT”: JL 1040, according to
Type „BA, WT“ Type „BB, LT“
EN 1561, Type “BB, LT ‘: JS1030, according to EN 1563.
The body has blue color (RAL 5000). Inside the body is a rubber liner made
of EPDM in accordance with an ISO 1691, the disc is made of carbon steel,
covered with nickel and the drive shaft spit into 2 parts is made of Stainless
Steel 1.4408 according to EN 10088.
The valves are available in Semi-lugged (type BA, WT) or Fully-lugged (type
BB, LF) versions.
